[cisco-voip] International Calls Not Working for Remote Site

[Johnny]

Hi Steven,

Is the gateway H.323 or MGCP? 

Check using "show voice call summary" on the gateway what codec is being
used. The gateway should be able to support G.729 calls although will
consume more DSP resource.

As another fix/work around you could create a new DP/Reg/Loc for the gateway
and specify that the codec between both the HQ site and the remote is G.711.

Kind Regards,

Johnny

I have this remote site which is an extension of HQ.  This site does
not have a voice gateway so it uses the HQ voice gateway to make
calls.  The issue is they can't seem to make international calls,
local and long distance work fine.

Each site has its own device pool, region, and location.

The only thing I can think of it might be a codec issue.  The reason I
say this is because for the remote site it chooses G.729 for all
sites, even within.  (I know it shouldn't be this, I inherited this
VoIP environment).  For the HQ it has G.729 for all sites except
within, it uses G.711.  So as a temporary fix I configured the remote
site phone with the HQ device pool and works fine.

I did some testing and when a call is made from the remote site to the
PSTN it uses codec G.729 local and ld calls work fine but not
international calls.

Any help would be greatly appreciated.

Thanks,
Steven Sarte
